That's only part of it -- the present names of both Charing Cross and
Embankment were also their original names on one line each.

Here's a table of the relevant openings, closings, and name changes.
For proper alignment view it in a monospaced font, of course. For CX
read Charing Cross, for E read Embankment, for TS read Trafalgar Square,
for S read Strand, for A read Aldwych. Line names have also changed
over the years, but I'll use the modern ones for simplicity's sake.
The separator "|" indicates separate stations.

What happened to what is now Charing Cross on the Northern between '73
and '76? Was it closed for Jubilee line works? Not something I had
ever appreciated before.

Reversing at Moorgate means eastbound trains cross the westbound line to

At Aldgate, there are two reversing platforms between the east and west
bound lines.
Reversing at Moorgate is uncommon. I assume it only happens when there
is unusual congestion around Aldgate.

If Crossrail ever happens, things will be more interesting as Moorgate
and Liverpool Street will be one station - the trains will be long.

IIRC, Moorgate was extensively refurbished in the late 1970s. It seems
a waste now. The LU terminating platforms have not seen much use. I
guess after Thameslink "whatever" the station could become a
subterranean shopping mall!! :-)

Not entirely true. They don't see much in the way of scheduled use but they
tend to get used very regularly during the peak hours for turning back
trains from any of the three lines that they serve, in order to better
regulate services - for example, to get late incoming Met services back on
diagram, rather than running through to Aldgate and causing knock-on delays.
In the (regular) event of signal failure in the Aldgate area they are used
for turning back all Circle and H&C services, in that event Met line trains
(other than those in the section between Baker Street and Moorgate) tend to
get turned back at Baker Street.
